System.IO.FileNotFoundException

Problem

You get this error when running your application:

System.IO.FileNotFoundException

This error may happen if you installed the Microsoft .NET Framework before you installed the Microsoft Internet Information Server (IIS).  The System.IO.FileNotFoundException indicates that a file is missing but is sure which file and why it would be missing.

Solution

We recommend you re-install Microsoft .NET Framework.  If you still get this error, re-register the .NET Framework by following the instructions in Re-Registering the .NET Framework.

The following explanation may be useful.  In particular, see the posting by "Dan (VS Core Team)".

If the problem persists, try:

Step 1:  Copy the file Microsoft.VisualBasic.DLL to your application's ...\Bin folder, and run the application again.

Step 2:  Give "write" permission for "Everyone" on the following folder on your Windows 2000 server:

C:\WINNT\Microsoft.NET\Framework\v1.1.4322\Temporary ASP.NET Files

Step 3:  After setting the permission to the folder, run your application created by Iron Speed Designer.

Step 4:  Repeat the process for this folder:

C:\WINNT\TEMP

Step 5:  Make sure the Microsoft Index Server is turned off.  Sometimes the Index Server locks the file and prevents you from accessing them when they are being indexed.
